Feature Limitations

MFF can be enabled in a maximum of 512 VLANs on the X series cards, E series cards (excluding EH1D2X48SEC0 card on S9700), BC card,
ACU2 card, and 64 VLANs on other cards.

When the number of MFF-enabled VLANs reaches the limit, the MFF function can still be enabled in other VLANs if there are ample ACL resources on the device.

To improve security, you are advised to perform the following configurations when configuring MFF:

Configure DAI in the corresponding VLAN.

Configure static binding entries for users connected to the device. (Run the user-bind staticip-addressstart-iptoend-ip command in the system view to configure static binding entries for all users connected to the device.)
